DESCRIPTION:In this talk I'll review several projects we worked on over th
 e last 2-3 years related to self-assembly of organic molecules on the gold
  surface and  NC-AFM imaging of Si(001) and Cu(110):O surfaces. In self-as
 sembly our primary interest is not only limited to studying assemblies geo
 metries and their energetics although due attention has been indeed devote
 d to this\, especially to the role the van der Waals interaction plays in 
 stabilising the networks\; we also studied kinetics of assemblies formatio
 n. Concerning the theme of NC-AFM imaging\, I'll consider two recent examp
 les in which the role of theory was crucial in interpreting the experiment
 : (i) flipping of Si dimers on the Si(001) surface with the tip\, and (ii)
  tip fingerprinting using the Cu(110):O surface. In the latter case we als
 o looked into thermodynamics of surface terminations where the role of the
  vdW interaction was found to be essential\, and I'll mention this as well
 \,\ntime permitting.
